Features to know about

Expanded Cargo Options: Built-In T-Slot Rails

When you need to haul more than what fits inside the bed, the integrated T-slot rails let you mount crossbars (sold separately) for your bikes, kayaks, or ladders. Because the T-slots are built into the rails, racks from brands like Thule, Yakima, and Rhino Rack slide right in without interfering with the retracting cover. It’s a clean, modular setup that keeps the bed free for other gear while giving you space above for extra cargo.

Secure Storage: Locking Retractable Aluminum Cover

The RetraxPRO XR uses 1" thick aluminum slats that can hold up to 500 lbs evenly distributed. They’re impact and weather resistant, and the matte black finish won’t fade or scratch easily. The pop-up locking handle lets you secure the cover anywhere along the rails, so you can protect tools or gear near the cab while leaving space for longer items at the tailgate. When closed and latched with the tailgate locked, it provides a strong barrier against theft and weather.

Smooth, Maintenance-Free Operation: Sealed Ball-Bearing Rollers

Instead of springs or hinges that wear out or freeze up, this cover rolls on sealed ball-bearing rollers that never need lubrication. It slides open with one hand using the pop-up handle, and retracts smoothly into a compact canister at the bulkhead. The spiral track inside the canister prevents the cover from rubbing against itself, avoiding scratches or binding.

All-Weather Protection: Sealed and Low Profile

Weather stripping and foam seals on all sides keep out dust, rain, and snow. The cover overlaps the top of the tailgate for added protection, and two drain tubes route any water out of the canister to keep it dry inside. The low-profile rails sit just 1" above the bed, giving the truck a clean, streamlined look while still offering clearance for most fifth-wheel setups.

Easy Installation: Clamp-On, No Drilling Required

Everything clamps directly to the bed rails—no drilling needed. The cover arrives preassembled inside its canister, so setup is straightforward. Just attach the rails, position the canister, tighten the clamps, and connect the drain tubes. Once installed, you get a durable, maintenance-free tonneau that looks great and handles real work every day.

I installed the RetraxPro XR tonneau cover myself and it wasn't bad at all. I had to do a lot of adjusting to get it perfectly straight and even. The hardest part was having my wife help me lift the cover in the truck after it was assembled. I wish they would include some kind of a reducer to be able to fit the drain hoses into the smaller holes in the bed of the truck so no drilling would have to be made. Other than that, great bed cover and can't wait to add T-slot accessories.

Was relatively simple to install and works as advertised. Not my first of these covers so I am a return customer and also new what to expect with installation. The PDF instructions are good, but not quite Lego or IKEA level. I haven't installed the Yakima HD Overhaul System yet, but do not expect any issues.

Easy to order and find the correct fit. This is my third cover from this brand and my first with aluminum slats instead of polycarbonate due to a different truck size. Installation took about two hours from start to cleanup, and I needed a couple of neighbors to help lift it since the aluminum version is heavier. My previous polycarbonate covers didn’t leak and worked well, but they became slightly wavy over time. I expect the aluminum version to hold up better.

Installation note for 2026 Ram 3500 Dually: when positioning the clamps at each set of plastic allen screws had to adjust front and back clamps The front clamp near the cab bolts were a bit short due to the wider gap between bed and tonneau rail, so I removed the top back piece of the clamp to secure it properly. The lower supports did not fully reach the side walls, and the rear clamp near the tailgate required removing the lower support bolt to clear the cargo light. The middle clamps fit as intended with no adjustments. Something for the manufacture to consider as new trucks come out with different accessories.

Overall, I’ve been very happy with this brand over the years and am satisfied with this purchase.

Thanks for sharing the install tip about the 2026 Ram 3500 Dually model. The Tonneau looks great on your truck too.

Love the rolling bed cover! No more lifting/folding heavy cover panels. Solid construction, easy to use, and relatively water tight. It is best to have a second person helping with the installation for lifting the assembled cover onto the bed of your truck without scratching the sides. Very easy to install.

And it looks sharp on your blue truck Marvin! I am happy you are very pleased with your new tonneau cover =)

by:
Replaced my "soft" tonneau cover that was tearing, fading, and falling apart after 10 years of faithful service. Bought this tonneau cover because of the retractable operation and the aluminum construction. While it is obviously built tougher and the operation is smooth, it does have its downfalls (which I didn't think of too much at the time). One being the space that is lost in the front where all that retraction goes, I guess there is around 8 inches of height at the very front. Additionally, where it lays is slightly lower than the bed rails which takes away at least around an inch of height compared to my previous cover. This makes a big difference when getting tall containers and the like to fit. I do enjoy the elevated level of security the new tonneau cover offers, even though I had zero problems with the previous cover.

Thanks for taking the time for such a detailed review RAMDaddy! I would say you definitely got your moneys worth on your last one with the 10 years of use! And valid points on the new cover, it does stink that the canister takes up so much room, but it is still a really nice cover. I hope you get 10 years plus out of this new one =)

by:
Quality and fit and finish seem strong. Straightforward install.
Would be 5 stars if the cover could close while using the Toyota tie-down system. The locking components knock up against the OEM tie-down brackets and stop the tonneau cover from closing.
Secondly, the OEM Toyota tie-down brackets cannot be used in the accessory T-slots as the OEM brackets have a larger T and cannot slide into the RetraxPRO accessory T-slots.

So,. I've paid for two different tie down systems , Toyota and Retrax and still don't have a solution. At my age I should have known better and done more research.

I couldn’t be happier with this tonneau cover for my F450. It shipped well, arrived quickly, and was packaged securely with no damage at all. Everything was organized and protected right out of the box.

Installation was surprisingly easy — clear instructions and no headaches. I had it mounted in no time, and it fit my F450 perfectly. The alignment was spot-on and the clamps secured tightly without any modifications needed.

The cover looks great, feels durable, and gives the truck a clean, finished appearance while keeping the bed fully protected. It opens and closes smoothly and feels solid once locked down.

If you’re looking for a tonneau cover for your F450, this is a great choice. Fast shipping, easy install, and excellent quality — 5 stars all the way!

Great fit. I had on on my old F150 and like the fit even more on my new Ram 2500.

Had this on my truck for over a year, outside in the elements every day and it still looks brand new. The finish is tough and durable. It rolls open and closed with ease and the locking mechanism is free and smooth. Couldnt be happier with it.

Retrax Pro XR with Rhino Rack Cross Bar set for the XR

This has greatly simplified my bicycle transport. Before I was using separate ladder rack on back of trailer, and hitch rack on truck. Compared with my prior setup, here are the improvements:
-- removes ~75 lbs from back of my trailer
-- not dealing with separate truck and camper bike racks (esp hitch rack taking up bed room while towing)
-- don't have to unload bikes to check something on camper roof
-- bikes are easier to load (even with lifting)
-- cross bars detach in seconds and lift off for full bed access or car wash (the cross bar and bike rack assembly stores on hook in garage)
-- Don't have to remove and store bike seats (they extended well past right side of trailer when on ladder rack)
-- Bikes are more protected above tonneau cover than either on hitch rack or ladder rack.
by:
Thanks etrailer. Ordered the Yakima Overhaul ladder racks and the Retrax tonneau cover. It’s the perfect solution for our camping/kayaking trips. Both products are solid and top notch. Installation was a breeze on my 20 Tundra.
by:
The Retrax Pro XR cover performs and looks like new after 1 year. Took 2 of us to install and adjust properly. Very minimal water leakage around tailgate sometimes which is expected. Read reviews of water leaks but must be due to improper installation/adjustment. Very satisfied and looks great. 2024 GMC 2500HD Denali

I had a solid tonneau before and liked it. Only problems with it were you could not drive with the cover up and it was a bear to remove even with the help of my wife. That truck was totaled by a drunk driver. So the replacement truck had to have an easier cover and wile I was at it, why not some racks as well?
It looks great! Fits perfectly and was a synch to install.
On the down side it is not completely dry and it did freeze up once in the winter. Other than that I do like it and gave it 4 stars

Really like this cover. Installation was fairly straightforward I was able to do the install myself but another person would have been helpful.
by:
Order was processed quickly and arrive in the specified shipping time. Easy two person install and fine tuning is an easy one person job. Great quality top and rugged. Perfect top for your pickup. Bed stays water tight so storing sleeping bags or luggage is no problem on long trips.
by:
Showed up quickly, this is the 3rd purchase from etrailer.com, they have great customer service, they know their products, prices are reasonable and they ship fast. I also purchased the Curt Hitch from them.
by:
Short version, LOVE IT!!! This was a lot more money than I wanted to spend but it was well worth it. While not water tight it is close. Easy to install, easy to operate. Does not make noise even on washboard roads. The loss of space by having a canister has not impacted me. But I saved the best for last. My daughter wanted one for her truck so I ordered another one. It was damaged in shipment and the best customer service representative in the world, Kimberly O, helped me out by getting me a new replacement quickly. I highly recommend this Tonneau Cover. I also got T-Slots and use my Rhino crossbars with the cover. No problems, just like they were made for each other.

Easy install nice and clean.

Wow! [whistles] that looks REALLY GOOD. Great fit on your truck!

by:
Works just as I had hoped.
by:
It is great. Took about 2 hours to install. You will need 2 people to put the assembled cover in the bed. I do have the multiplex tailgate and rain water will get into the bed because of the gap in the tailgate sections.
by:
It doesn’t lock into any position very well, either have all the way open or close. At time after I unlock it then I have to open the tail gate pull it to get it to unlock.

  • Correct XR/Trax Rails to Add to RetraxPRO MX Hard Tonneau Cover RT80367
    The Replacement Side Rails # RT94FR is indeed the right product to add XR/Trax Rails to your existing PRO MX Hard Tonneau Cover # RT80367. This will allow you to add T-slot accessories like crossbar systems to the cover. The rails themselves are technically the replacement XR Rails for the PRO XR Hard Tonneau Cover # RTT-80323, but can also be added to your MX model to upgrade the setup.
